The Z202-H module measures the value of the alternating voltage applied to the input terminals, converting it into a normalized current or voltage signal at the output terminals. The instrument stands out for its precision class and high input impedance. 10..490 Vac alternating voltage input in 41 pre-calibrated scales, selectable via terminals and DIP-switches. The Z202-H provides the possibility of calibrating and extending each scale to the next, allowing calibration at any full scale in the continuous range 0..500 Vac, without either decalibrating the fixed ranges or opening the instrument (multi-turn trimmer accessible from the front panel).
